The following subsections describe omissions or new information that will be added to the next publishing of the Hardware Guide.

Dynamic Reconfiguration Operations For Sun Cluster Nodes

The Sun Cluster 3.0 12/01 release supports Solaris 8 dynamic reconfiguration (DR) operations on qualified servers. The current Sun Cluster 3.0 12/01 Hardware Guide does not specifically consider scenarios in which the cluster nodes have been enabled with the DR feature.

In the Sun Cluster 3.0 12/01 Hardware Guide, some procedures require that the user add or remove host adapters or public network adapters in a cluster node. Contact your service provider for a list of storage arrays that are qualified for use with DR-enabled servers.

Review the documentation for the Solaris 8 DR feature on your hardware platform before using the DR feature with Sun Cluster software. All of the requirements, procedures, and restrictions that are documented for the Solaris 8 DR feature also apply to Sun Cluster 3.0 12/01 DR support (except for the operating environment quiescence operation).

Documentation for DR on currently qualified server platforms are listed here.

DR Operations in a Cluster With DR-Enabled Servers

Some procedures in the current Sun Cluster 3.0 12/01 Hardware Guide instruct the user to shut down and power off a cluster node before adding, removing, or replacing a host adapter or a public network adapter (PNA).

However, if the node is a server that is enabled with the DR feature, the user does not have to power off the node before adding, removing, or replacing the host adapter or PNA. Instead, do the following:

1. Follow the procedure steps in the Hardware Guide, including any steps for disabling and removing the host adapter or PNA from the active cluster interconnect.

   See the Sun Cluster 3.0 12/01 System Administration Guide for instructions on removing cluster host adapters (transport adapters) or PNAs from the cluster configuration.

2. Skip any step that instructs you to power off the node, where the purpose of the power-off is to add, remove, or replace a host adapter or PNA.

3. Perform the DR operation (add, remove, or replace) on the host adapter or PNA.

4. Continue with the next step of the procedure in the Hardware Guide.

For conceptual information about Sun Cluster 3.0 12/01 support of the DR feature, see the Sun Cluster 3.0 12/01 Concepts document.

Sun Netra st D1000

The Netra^TM st D1000 has been qualified for use with Sun Cluster 3.0, but maintenance procedures do not yet exist in the Sun Cluster 3.0 12/01 Hardware Guide specifically for the Netra st D1000. However, you can use the existing Sun Cluster 3.0 12/01 Hardware Guide procedures for the StorEdge D1000 to maintain a Netra st D1000 in a cluster environment. Substitute the following document references in place of the StorEdge D1000 document references if you are maintaining a Netra st D1000.

• Netra st A1000 and Netra st D1000 Installation and Maintenance Manual (805-7147)

• Netra st A1000 and Netra st D1000 Product Notes (805-7148)

Sun StorEdge T3/T3+ (Partner-Group Configuration)

Quorum Device Restriction Removed

When the Sun Cluster 3.0 12/01 Hardware Guide was published, it noted a restriction against using Sun StorEdge T3/T3+ arrays as quorum devices, when the arrays are used in a partner-group configuration.

That restriction has since been removed. That is, you can use Sun StorEdge T3/T3+ arrays as quorum devices, whether the arrays are used in a partner-group configuration or a single-controller configuration.

Sun StorEdge T3/T3+ (Single-Controller Configuration)

The Sun Cluster 3.0 12/01 Hardware Guide chapter on "Installing and Maintaining a Sun StorEdge T3 or T3+ Array Single-Controller Configuration" incorrectly indicates that the procedure for upgrading a Sun StorEdge T3 array controller to a Sun StorEdge T3+ array controller does not require any cluster-specific steps. The correct procedure should be as follows.

How To Upgrade a StorEdge T3 Controller to a StorEdge T3+ Controller

Perform this procedure on one array at a time. This procedure requires that you take the array in which you are upgrading the controller offline. If you take more than one array offline, your cluster will lose access to data, if the arrays are submirrors of each other.

1. On one node attached to the StorEdge T3 array in which you are upgrading the controller, detach that array's submirrors.

   For more information, see your Solstice DiskSuite^TM or VERITAS Volume Manager documentation.

2. Upgrade the StorEdge T3 array controller to a StorEdge T3+ array controller.

   See the Sun StorEdge T3 Array Controller Upgrade Manual for instructions.

3. Reattach the submirrors to resynchronize them.

   For more information, see your Solstice DiskSuite or VERITAS Volume Manager documentation.
